Abstract

In this paper, new ranges of GaAs MMIC circuit applications at microwaves are presented with the development of original planar active filters in this technology. The first step is to improve intrinsic performances of planar microstrip resonators with the help of MMIC amplifier or negative resistance chips [1]. Finally, a novel active recursive structure is also demonstrated as an MMIC.
